FIELD OF DISCLOSURE

The present disclosure generally relates to digital data processing. More specifically, the disclosure relates to a method and system for estimating a Region Of Interest (ROI) corresponding to a plurality of content streams.

BACKGROUND

As users increasingly turn to the internet for all their information needs, there is a constant pressure on information providers to expand their databases with newer data. One example of such data relates to events. Accordingly, there are several information providers who maintain event databases that inform users about a time and a place where an event (e.g., a sporting event, a music concert, a conference, etc.) is scheduled to occur. Additionally, such event databases may also include information about currently ongoing events and/or completed events. Further, in case of events that are completed, a recording (audio, video, multimedia etc.) of the event are typically available to users.

However, conventionally, such event databases are constructed and maintained largely based on manual efforts. For example, content reviewers scour various communication channels (e.g., newspapers, magazines, direct communication from event organizers, radio, television, advertisements etc.) in order to identify events and accordingly update an event database.

Firstly, the manual process of discovering events and updating event databases is cumbersome and time consuming. Typically, individuals delegated with the task of searching and identifying events and associated event information (type of event, time, place, etc.) are burdened. Further, while some event databases allow general users to provide such event information (i.e., crowdsourcing of event information), reviewing such information for correctness is still a difficult and time consuming process.

Secondly, due to the limited number of communication channels that are searched by content reviewers, a large number of interesting events that are not advertised on such communication channels are missed. For example, there may be several local events which may not garner an advertising campaign. However, users situated in the vicinity of such events may nonetheless be highly interested in these local events.

Thirdly, some events may occur on an ad-hoc basis and/or in an unorganized manner, which thus makes it difficult to collect and provision corresponding event information to users in a timely fashion.

Further, while currently there are techniques of aggregating content streams based on location, topic, etc., such aggregation of content streams may not necessarily correspond to an event. For example, at a place with high tourist foot-fall, a large number of users may be capturing and streaming video of different regions and/or subjects which may not correspond to a singular event.

Fourthly, while an event may be spread across a large spatial region, there may be one or more smaller regions of interest at different times during the event's progression. For example, at an event involving a large stage, interesting action may take place on different regions of the stage at different times. However, existing methods do not provide an automatic and reliable way of determining such regions of interest for a user's benefit.

Lastly, while users are currently offered the ability to consume a video recording of an event from different viewpoints, there is no intuitive user interface that enables users to effectively navigate across multiple viewpoints to experience the event from different perspectives.

Accordingly, there is a need for methods and systems for automatically discovering events and identifying regions of interest in such events in a manner that overcomes one or more of the above-mentioned drawbacks.

The present disclosure includes many aspects and features. Moreover, while many aspects and features relate to, and are described in, the context of content streams such as live audio/video streams, embodiments of the present disclosure are not limited to use only in this context. For instance, the methods and systems disclosed herein may be used to aggregate any digital content based on corresponding metadata (for example, but not limited to, sensor data) associated with the digital content.

I. Platform Overview

Consistent with embodiments of the present disclosure, methods, computer-readable media, and systems for Region of Interest (ROI) estimation and representation (also referred to herein as “platform” or ROI estimation platform) may be provided. Estimation and/or representation of a ROI may at least be based on sensor data including location data and orientation data corresponding to recording devices. This overview is provided to introduce a selection of concepts in a simplified form that are further described below. This overview is not intended to identify key features or essential features of the claimed subject matter. Nor is this overview intended to be used to limit the claimed subject matter's scope. The platform may be used by individuals or companies to estimate ROI based on sensor data, such as, location data and orientation data corresponding to recording devices. Thus, according to exemplary aspects, the present disclosure provides methods, systems, and/or techniques for discovering an event and a region of interest associated with the event.

In another exemplary aspect, the present disclosure describes techniques of estimating a ROI using data provided by location and orientation sensors built into a smart mobile device to determine a live stream point of view (POV). The POVs from multiple smart mobile devices at the same relative location or venue can be analyzed to determine the Region of Interest (ROI) for an event at that location. The ROI can then be visualized graphically on a viewer's smart mobile device or television to aid in understanding an event's location with no prior knowledge of the size and shape of the venue.

In another exemplary aspect, the present disclosure provides a method to collect and analyze a plurality of data streams to compute an approximate size and shape of the ROI at a venue with no previous knowledge of the venue. In some aspects, two or more people may be present at the venue and that two or more of the people are pointing the camera on their smart mobile devices at something within the ROI. In further aspects, the accuracy of the computed area and/or volume may be relative to the number of people pointing their devices at the ROI. The method can be used to calculate two-dimensional or three-dimensional volumes.

In various aspects, each person's mobile smart device, such as a modern smart phone, tablet, or wearable includes sensors to measure global position, compass heading, and acceleration of movement in three dimensions. The data from each of these smart mobile devices, in addition to the make and model of the device, can be streamed over a collection of wireless and wired networks to a computer server and data storage. The server can then process the data from each device. The global positioning system coordinates can be converted to an origin point in a mapping coordinate system. The compass heading angle can be converted to a vector, or specifically a direction from the origin point. The combination of the origin point and the vector can mathematically represent the position and direction that the person is pointing their smart mobile device, relative to other people's devices at the venue.

In further aspects, an array of previously collected data about the make and model of smart mobile devices can be used to provide lens characteristics for the specific smart mobile device. The lens characteristics can be used to determine the ever-expanding field of view (FOV) for the specific smart mobile device's camera. In yet further aspects, the FOV can be represented geometrically as an expanding square frustum.

In further aspects, the origin points of all smart mobile devices collecting data at the venue can be placed in the same coordinate system so that their position is accurate relative to the position of the actual people pointing their devices in the real venue. In some aspects, a two-dimensional line segment representing the length or magnitude of the directional vectors for each device can be extended from their origin point to a pre-estimated maximum length, less than infinity, to cover the size of a very large venue, such as a stadium or park.

Intersections of these vectors can represent shared areas being pointed at by people. The specific camera frustum can be overlaid onto each smart mobile device's origin point with the directional vector as the center expanding direction of the frustum. In still further aspects, the outer edges of the intersections of the expanded view areas can be connected to form a polygonal representation of the shared ROI.

In some aspects, such as where devices appear to be pointing from one side of a 180° line, such as with a smaller concert venue or amphitheater, the closest interior origin point can be used to estimate the beginning depth of the ROI. In further aspects, the type of event, such as a concert, could be used to estimate the maximum depth of the ROI.

In other aspects, such as where devices appear to be pointing from all sides, such as a stadium or large sporting event, a center point or centroid can be computed from all origin points. In further aspects, the distance from the centroid can be computed for every origin point. In still further aspects, a number of directions can be sampled, such from greater than one, for example, four or sixteen. In yet further aspects, the closest origin point from the centroid in every sampled direction can be connected to estimate the containing shape of the ROI.

In further aspects, the region of interest is at least based on analysis of content streams captured by multiple recording devices (e.g., smartphone cameras, portable cameras, wearable cameras, etc.) from different viewpoints. In still further aspects, data related to positions and orientations of multiple recording devices can be analyzed to determine a Region Of Interest (ROI) towards which the multiple recording devices are pointed. In yet further aspects, determination of the ROI can further comprise discovery of an event captured by users of the multiple recording devices. In even further aspects, optical characteristics (e.g., field of view) of the multiple recording devices can be utilized to determine attributes of the ROI such as, size, shape, volume, etc. As a result, a graphical representation of the ROI may be provided to users depicting a spatial form of the ROI with relative positions of the multiple recording devices. Such a graphical representation may allow users to intuitively visualize the ROI and other available viewpoints of the ROI. Thus, in conjunction with access to content streams captured by the multiple recording devices, users may be provided with an intuitive and powerful user interface for navigating across multiple viewpoints and consuming the content streams that include the ROI.

In further aspects, the multiple recording devices may be configured to capture and transmit sensor data representing position and orientation of respective recording devices. Accordingly, each recording device may include a position sensor (e.g., GPS sensor) and an orientation sensor (e.g., magnetic compass). In still further aspects, the sensor data may include a time indicator corresponding to sensing of the position and orientation of respective recording devices. Such sensor data may, in some aspects, be transmitted along with content (e.g., video, audio etc.) captured by respective recording devices.

According to various aspects, the sensor data may be processed by one or more computing devices or recording devices in connection with one or more stages of the disclosed methods and systems. For example, the sensor data may be embedded as metadata in a content stream captured and transmitted by a recording device, such as a smartphone. In further aspects, the smartphone may be provided with an app configured for capturing and transmitting the sensor data to a computing device, such as central computing device, for example, a server. In still further aspects, the app may be configured for embedding the sensor data during capturing of content. In yet further aspects, the recording devices may be configured to only transmit sensor data along with corresponding time indicators to indicate a respective time (e.g., date and time of day) when the sensor data was captured.

In further aspects, transmitted sensor data in multiple content streams may be received by a central computing device, such as a server. In some aspects, the server may process or sort the multiple content streams according to one or more attributes such as, location, time, orientation, etc. By way of non-limiting example, initially, the server may process or sort the multiple content streams based on temporal and spatial proximity. To this end, content streams which were captured within a short time window (e.g., few hours, minutes, etc.) and at a common place (e.g., a sports stadium, amphitheater, concert venue, etc.) may be aggregated. In other aspects, transmitted data from can also be received and processed by another smartphone (e.g., another user of the platform). For example, a user of the disclosed platform and systems may receive and utilize data transmitted from another user's smartphone (e.g., a different user viewing a common event) to determine and produce an ROI. In further aspects, the shared data can be unprocessed sensor data, or data processed by a user to determine a ROI, or combinations thereof.

Further, sensor data (i.e., position and orientation) in the multiple content streams may be analyzed in order to determine one or more ROIs. Accordingly, each recording device may be represented as an origin point in a coordinate space constructed by the server. Accordingly, the positions (i.e., geographical locations) of the multiple recording devices may be mapped in the coordinate space while preserving a spatial relationship among the positions. For example, a first recording device, a second recording device and a third recording device may be away from each other by 100 m. In other words, the three recording devices may be located at vertices of an equilateral triangle. Accordingly, three origin points may be created in the coordinate space with the same spatial relationship. In other words, the three origin points may be equidistant from each other.

Further, each origin point may be associated with a vector (2D or 3D vector) representing an orientation of a respective recording device. In further aspects, a first recording device may be represented by a first origin point and a first vector in the coordinate space, wherein spatial coordinates of the first recording device is based on position of the first recording device, while a direction of the first vector is based on orientation of the first recording device. In still further aspects, each of the vectors may be extended indefinitely or until they reach a surface of a bounding box of the coordinate space. In yet further aspects, the bounding box may be of arbitrary form and significantly larger than the biggest ROI determinable.

Subsequent to extending the vectors corresponding to the multiple origin points, intersections among the vectors may be determined. For example, given a first origin point and a first vector corresponding to the first origin point, a first line in the coordinate space may be computed. Similarly, a second line may be computed based on a second origin point and a second vector. Further, using coordinate geometry, it may be computationally determined whether the first line intersects the second line within the coordinate space. Further, an intersection point corresponding to the first line and the second line may also be computationally determined. Accordingly, multiple such intersection points may be determined corresponding to a plurality of pairs of lines. Further, in some aspects, lines may overlap each other resulting in a plurality of intersection points for a given pair of lines. Furthermore, the number of such intersection points may be based on a sampling distance in the coordinate space.

In further aspects, a spatial distribution of the intersection points may be computationally analyzed. Accordingly, one or more spatial characteristics associated with the multiple intersection points may be computed. For example, a density of intersection points at various points within the coordinate space may be computed. Accordingly, spatial regions with density exceeding a threshold value may be identified as being coincident with the ROI. In other words, a spatial concentration of intersection points can, in various aspects, indicate presence of the ROI. Additionally, a spatial distribution of the intersection points may indicate attributes of the ROI, such as, shape, size, area, volume, etc. Accordingly, in some aspects, by computing a boundary associated with the spatial concentration of intersection points, a shape of the ROI may be determined. Further, attributes of the ROI such as area and volume may then be computationally determined based on the boundary.

Further, by considering one or more optical characteristics of the multiple recording devices, estimation of the ROI may be performed with higher accuracy. For example, field of view (FOV) corresponding to the multiple recording devices may be taken into account in determining the ROI. Accordingly, the multiple recording devices may be configured to transmit respective FOV values to the server. Alternatively, the multiple recording devices may be configured to transmit device information (i.e., model number, product code etc.) based on which the server may determine corresponding FOV values by performing a database search.

Subsequently, for each origin point and corresponding vector, a viewing frustum (2D or 3D) may be constructed in the coordinate space at least based on a FOV value associated with the origin point. Further, an apex of a viewing frustum associated with a recording device may be coincident with an origin point associated with the recording device. Furthermore, a view direction of the viewing frustum may be aligned with the vector associated with the origin point. Subsequently, a plurality of intersections of multiple viewing frustums may be determined. Such determination may be performed computationally using coordinate geometry. Further, by computationally analyzing characteristics of the plurality of intersections of viewing frustums, the ROI may be estimated.

Subsequent to determining the ROI, a visualization of the ROI may be generated by the system. The visualization of the ROI may be a geometrical FIG. 2D or 3D) depicting the shape and orientation of the ROI. For example, a performance stage which may be of circular form may be represented as a circle in the visualization. Additionally, the visualization may include visual representation of the multiple recording devices according to respective positions in relation to the ROI. In other words, the visualization of the ROI may also depict where the multiple recording devices are spatially situated in relation to the ROI. As a result, the visualization enables users to view a spatial form of the ROI and also the multiple viewpoints that are available. Accordingly, a user may select a representation of a visualization in the particular recording device in order to express an interest in a corresponding viewpoint. In some aspects, the visualization may be configured to receive user inputs associated with different regions of the visualization. For example, the visualization displayed on a touch-screen may be configured to receive touch inputs on points corresponding to the multiple recording devices. Consequently, the content stream captured by the particular recording device may be retrieved and displayed to the user. As a result, the visualization may function as a spatial user interface that may enable users to intuitively navigate across multiple viewpoints and consume corresponding multiple content streams.

According to further exemplary aspects, the present disclosure provides at least two methods related to live streaming events. A first method includes collecting, streaming, and collectively analyzing sensor data from the smart mobile devices of live streamers at the same event to determine and visualize the relative position and orientation of the streamers. A second method includes using that data and analysis to estimate the size and shape of the Region of Interest being covered by the collection of live streamers.

As described herein, determining an estimated ROI has several benefits. In further aspects, a use related to live streaming events enables a user interface element to visualize multiple available viewpoints around the most likely Region of Interest. In still further aspects, this aids the user in understanding the likely size and shape of the volume that they are navigating when exploring multiple points of view around an event.

Accordingly, a plurality of users 204 (such as 204 a, 204 b and 204 c) may be situated at different locations in relation to the area 202. Further, the plurality of users 204 may be recording the event with a plurality of recording devices (such as 206 a, 206 b and 206 c). Examples of recording devices may include, but are not limited to, smartphone cameras, digital cameras, IP cameras, tripod mounted cameras, CCTV cameras, sound recording devices, etc. Furthermore, the recording devices may include one or more sensors such as, but not limited to, location sensor (e.g., GPS receiver), orientation sensor (e.g., electronic compass), a motion sensor (e.g., accelerometer), a speed sensor etc. As a result, the recording devices 206 may generate a stream of sensor data and/or a stream of content (e.g., audio, video, multimedia). Further, such streams of sensor data and/or content may be time-stamped based on a standard time base (e.g., time provided by cellular network provider). Alternatively, each of the plurality of recording devices 206 may include an application configured to receive a synchronization data in order to synchronize a local timer with an external standard timer (e.g., a timer on a server). As a result, the stream of sensor data and/or content may be correlated in time. In other words, a given time instant, sensor data from each of the plurality of recording devices 206 may be identified and collected.

The area 202 is an example of a Region Of Interest (ROI) as referred to in the present disclosure. Further, the methods and systems disclosed herein estimate the ROI based on the stream of sensor data and/or content captured by the plurality of recording devices 206. In an instance, the ROI is estimated based on locations of the plurality of recording devices 206 and the orientations of the plurality of recording devices 206. Accordingly, location and orientation may be represented geometrically in the form of origin points and vectors for facilitating estimation of the ROI.

Specifically, FIG. 3 illustrates construction of origin points corresponding to locations of the mobile devices and vectors corresponding to the orientation of the recording devices for ROI estimation, in accordance with some embodiments. Based on location data corresponding to the plurality of recording devices 206, a plurality of origin points 302 may be constructed. For example, origin point 302 a corresponding to location of recording device 206 a, origin point 302 b corresponding to location of recording device 206 b and origin point 302 c corresponding to location of recording device 206 c may be constructed. In an instance, the location data may be two-dimensional and include latitude and longitude. In another instance, the location may be three-dimensional and accordingly include latitude, longitude and altitude. Accordingly, a corresponding coordinate space (i.e., 2D or 3D) may be constructed. Further, co-ordinates of the plurality of origin points 302 may be identical to the corresponding latitude, longitude and altitude values of the location data. Alternatively, in an instance, the latitude, longitude and altitude values may be normalized in order to generate the co-ordinates of the plurality of origin points 302. In other words, a spatial frame of reference for the plurality of origin points 302 may be different from that of the location data.

Further, based on orientation data corresponding to the plurality of recording devices 206, a plurality of vectors 304 may be constructed. For example, vector 304 a representing the orientation of recording device 206 a, vector 304 b representing the orientation of recording device 206 b and vector 304 c representing the orientation of recording device 206 c may be constructed. Further, based on the dimensionality of the location data, the plurality of vectors 304 may be 2D or 3D. Furthermore, in some instances, the dimensionality of both the plurality of origin points 302 and the plurality of vectors 304 may be less than the dimensionality of the location data and the orientation data.

Further, the plurality of vectors 304 may be extended to allow for intersection between the plurality of vectors 304. Based on the intersection points between the plurality of vectors 304, the ROI may be estimated. For example, a high spatial density of intersection points may be an approximate indication of the ROI. However, in order to determine the ROI with greater accuracy, field of views of the plurality of recording devices 206 may be taken into account.

Accordingly, FIG. 4 illustrates ROI estimation based on construction of origin points corresponding to locations of the recording devices, vectors corresponding to the orientation of the recording devices and 2D viewing frustums centered on the origin points, in accordance with some embodiments. As illustrated, a plurality of viewing frustums 402 corresponding to the plurality of recording devices 206 may be constructed in the coordinate space. For example, viewing frustum 402 a corresponding to recording device 206 a, viewing frustum 402 b corresponding to recording device 206 b and viewing frustum 402 c corresponding to recording device 206 c may be constructed based on optical characteristics, such as, but not limited to, Field of View (FOV) of lens comprised in recording device 206 a, 206 b and 206 c respectively. Accordingly, the FOV values of the recording devices 206 may be determined and transmitted by the recording devices 206 along with location data and orientation data. Alternatively, the recording devices 206 may be configured to transmit device information (e.g., model number, product code etc.) which may enable the platform 100 to automatically identify the corresponding FOV values by querying a device information database.

Accordingly, based on a FOV value of a recording device 206, a corresponding viewing frustum 402 may be constructed centered on the corresponding origin point 302 and oriented along the corresponding vector 304. For example, viewing frustum 402 may be constructed with the center point proximal to the origin point 302 a while the orientation of the viewing frustum 402 is along the direction of the vector 304 a.

Subsequently, the viewing frustums 402 may be extended to allow for intersections. Accordingly, a plurality of intersections 404 (e.g., 404 a-e) between the viewing frustums 402 may be formed. Thereafter, by interconnecting intersection points 404 lying on the periphery of a cluster of intersection points 404, the ROI 406 may be estimated. In some embodiments, certain intersection points 404 may be excluded from consideration by taking into account prior knowledge about spatial characteristics of a venue where the plurality of recording devices are situated. Additionally, in some embodiments, the ROI may be approximated based on closest match to a predetermined shapes of areas (e.g., rectangular, spherical, elliptical, etc.).

FIG. 5 illustrates ROI estimated based on construction of origin points corresponding to locations of the recording devices, vectors corresponding to the orientation of the recording devices and viewing frustums centered on the origin points, in accordance with some embodiments. As illustrated, the ROI 502 may be determined based on spatial distribution of intersection points corresponding to intersection of the plurality of viewing frustums 402.

FIG. 6 illustrates estimation of ROI based on calculating a distance between a recording device and an object within the ROI using image analysis, in accordance with some embodiments. As shown, the event may be taking place in a physical space 602 involving one or more objects 604 (e.g., a person). Further, the object may be associated with a spatial dimension 606, such as, for example, height. When the event is captured by a recording device 206 (e.g., 206 a), an image 608 of the object 604 may be formed. Further, a spatial dimension 610 of the image object 604 may be determined using image analysis. Moreover, by using image analysis, the real world object corresponding to the image object 604 may be determined. In other words, image analysis may be performed to identify one or more objects being captured by the recording device 206. As a result, based on prior knowledge about spatial characteristics of various objects, the platform may calculate a distance 612 between the recording device 206 a and the object 604. For instance, once the object 604 is detected to be a human, a predetermined average height of the human may be used in computing the distance 612.

Accordingly, distances between recording devices 206 and one or more objects 604 in the ROI may be computed. These distances may then be taken into account in estimating the ROI. In particular, by utilizing these distances, a shape and/or size of the ROI may be calculated more accurately.

FIG. 7 illustrates estimation of ROI based on calculating a plurality of distances between a plurality of recording devices and an object within the ROI using image analysis, in accordance with some embodiments. As illustrated, the event may involve a physical space such as a stage upon which one or more objects 702 (e.g., persons 702 a and 702 b) may be performing. Further, the event may be captured by multiple recording devices, such as, recording devices 206 a, 206 b and 206 c. Additionally, by utilizing image analysis (as explained in conjunction with FIG. 6), a plurality of distances 704 (e.g., 704 a, 704 b and 704 c) may be computed between the plurality of recording devices 206 and the one or more objects 702. Subsequently, by taking into account the plurality of distances 704, a shape and/or size of the ROI may be calculated more accurately.

FIG. 8 illustrates construction of origin points corresponding to locations of the recording devices, vectors corresponding to the orientation of the recording devices and 3D viewing frustums centered on the origin points for ROI estimation, in accordance with some embodiments. As illustrated, a plurality of 3D viewing frustums 802 (e.g., 802 a, 802 b and 802 c) may be constructed corresponding to the plurality of recording devices 206. Further, each 3D viewing frustum may be centered co-incident with a corresponding origin point. For example, 3D viewing frustum 802 a is constructed with its center point coincident with the origin point 302 a associated with the recording device 206 a. In other words, an apex of a 3D viewing frustum 802 associated with a recording device 206 may be coincident with an origin point 302 associated with the corresponding recording device 206. Furthermore, a view direction of the 3D viewing frustum 802 may be aligned with the corresponding vector 304 associated with the origin point 302. Subsequently, a plurality of intersections of multiple viewing frustums 802 may be determined. Such determination may be performed computationally using coordinate geometry. Further, by computationally analyzing characteristics of the plurality of intersections of viewing frustums 802, the ROI may be estimated.
